A method of using a protective apparatus with an intravenous system and especially an implanted intravenous needle assembly or a Y-junction of a piggy back intravenous system. The protective apparatus includes a protective sheath having an open end and a second end suitable for connection with a fluid introduction source. The sheath includes a slot along its lowest surface and can include a needle extending within a hollow interior defined by the sheath. The sheath features two curved runner sections or a pair of wing-shaped runners which extend from a channel section defining a portion of the slot. The curved runner sections and wing-shaped runners allow for easy insertion of a needle into a taped receptive port of an implanted intravenous needle assembly. An alternate embodiment features two slits with or without an additional channel/elongated aperture combination. The two slits allow for easy insertion of a needle into a taped receptive port while the channel/elongated aperture combination allows for use of the protective sheath with a Y-junction of an intravenous system. An additional embodiment features a needle assembly with protective guard that can be easily connected within the interior of the protective sheath.
